zThis invention relates to railway'cars andl has particular referencetoarticulated cars in.

adjacent endfy portions oftwo car bodies arel supported-by.afcenterplatecarried by a truck bolster,ythe axis of horizontalswiveling being defined by. .af king bolt or. pivot pin secured to thebOlster'and-'deining the support for al foot plate which spans theadjacent fend portions fof therca-r bodies.. l

IOther obje'ctsand,v advantages'of this in! vention will be apparentfroniithe following' description taken with the accompanying drawingsin-which Figure -lfis atop plan'view of the adjacent end portionsOfftWo-carf bodies,ia'part of the figure being taken o'n'the lline 1:1',Fig. 2. Y Fig. 2 is asetional view through the adjacent end portionsoftlie cari bodies, the view showing the articulatedjoint` and'alsoshowing, diagrannnatically, a portion 'of a car-V truck.V 1 y Fig; 3"isa top plan view of the center plate, and

' Referring` nowmore yparticularly to the drawings in which'similarcharacters of ref'- erence designate similar parts inltheseveral views,inasmuch as fthe inventionfmay'be applied to almost any `desired'form ofcar body, the construction of tliebody above the underframeis notillustrated. The bodies are providedwith underfraines which includespaced center sills 2,'ch'annel'ishaped in the instance shown, overWhichendjloor sheets alare an ranged,- andibet'ween. the center sillsbody connection castings A and B,-respectively,are.

1931. Serial No. 544,434.

which latter a portion E is illustratedy diaf grainmatically.

As more clearly shownin Fig.v 2, thefbolster D is of box formation andintermediate. its ends is provided withan apertured guider lug 6concentrically arranged with respect to an annular vertical rib 8,saidlug (iand'rib 8 defining therebetween an annular recess 9l whichreceives the center plate-C, the latter supporting the adjacent endportions of the car bodies. f

The center plate C is substantially circular insliape and comprisesahollow casting/having an annular supporting ange l0 forinedf with anddepending from' its lowerv 'Wall' A12; ther flange'lO fittingA thebefore mentioned recess -9 and positioning they center plate, as willbefappare'nt. The upper wall 14 ofthe casting C is provided with anannular recess' 16 into which arcuate bearings lS--forrnedl with thelower Walls 20 of the castings A and B eXtendwhereby the adjacentend'portions of the car bodiesrare supported for horizont tall swivelingin the centerl plate.

The end portions of castings A and Bare formed intoaperturedprojectionsV22 and24, respectively, which lap eachotherinspacedl relation and which are alined, as more clearly, shown inFigs.l and 2, to receive a king bolt or pivot' pink 26 which yextendstherethrough and through the centerplate'C (the upper and lower wallsthereof being centrally aperitured) ,'and'through the bolster D; thepivoty pin 26 beingr secured to the bolster in` any suitable manner. Intheinstance shown,.thev lower end of the pin 26 carries a nut28 Awhichis threadedly engaged in the lower or bottomwall 30 of the bolster, andlis provided for they purpose of securing the pin `26 Vto the bolster.y

In articulated car construction it is'necessary to provide a means forpermitting ltransfer of passengers from onecar body tol the other andlinthe car of the present invention a foot rplate 34 isprovidedwhichspans-'the space between the adjacent car bodies and'is mounted on andsecured to the upper end of4 the pin 26 in any suitable manner, as shownat 36; the foot plate 34 overlapping'the end cover plates 3, as clearlyshown in Fig.' 2S

In use, itlwilLbegapparent thatthe respective car bodies may swivelhorizontally relative to each other due to the supporting thereof by thecenter plate C and the body connection castings A and B. Excessive relative vertical shifting of the car bodies is prevented by reason of thefixed connection of the pin 26 in the bolster D, and the foot platesupporting bracket 38 secured to the foot plate 84. It Will be apparentthat excessive sidewise shifting of the respective car bodies isprevented by reason of the arcuate formation of the bearing members 18and their engagement with the center plate C. To disassemble theconstruction shown, the nut 28 is removed whereupon the foot plate 34and pin 26 may be removed by lifting the same vertically out ofconnection with theF projections 22 and 24 and the center plate and theneither or both oi the car bodies may be removed from their engagementwith the center plate C.

The drawings herein illustrate one embodiment of the invention, but itis to be understood they are for illustrative purposes onlyI and variouschanges in the form and proportions of the construction shown may bemade within the scope of the appended claims Without departing from thespirit of the invention.
